ENGINE VALVE MECHANISM.

Specification of Letters Patent.

Application filed J'u1y12, 1910. Serial No. 571,594.

T 0 all whomii may concern:

lie it known that I, ()soAn Tnninn, a citi-' r of the motive agent at the valves.

For the purpose mentioned, use is made of a hollow valve for the passage of the motive agent (either live or exhaust), and the valve is adapted to engage a yieldingly mounted cap for closing or opening the hollow Valve.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in

which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the valve mechanism as applied to internal combustion engines; Fig. 2 is a cross section of the same on the line 22 of Fig. 1; and Fig. 3 is a side elevation of part of the cylinder, showing more particularly the pas-.

sage for the pivotal connection of. the valveactuating mechanism.

In the cylinder A of the engine is mounted to reciprocate the piston B, and the upper end or working chamber of the cylinder A is connected with the chan'ibers C and C, one being the admission chamber and the other the exhaust. chamber, the chambers connecting with the chests I), D, the latter being surrounded by a water jacket E,which also surrounds the cylinder A, at its upper; portion, as plainly indicated in Fig. 1. In the chests l.) andl) are mounted to slide hollow valves F and F, pivotally connected with rods Gr, G supporting friction rollers H, H, in peripheral engagement with cams I, I, secured on cam shafts J, J, driven from and rotating in unison with the en 'ine shaft. The lower ends of the rods G an G" are pivotally connected with coupling links K, K, fulcrumed on the engine bed, and springs L press on the rods G, G, to hold the friction rollers H, H in peripheral contact with the cams I, 1, respectively.

The upper ends of the valves F, and F, are provided with valve seats F F adapted to engage opposite valve seats N N formed on the bottom of caps N, N, mounted to slide in chambers D D arranged on the top of the chambers C and C. The caps N and N are pressed on in a downward direction by springs O, 0, held in the chambers D D and engaging nuts P, P, screwing in the upper ends of the said chambers. Now by adjusting the nuts P, P,

the tension of the springs O, O can-be regu- Patented July 4:, 1911.

lated. Jam nuts 1, P serve to lock the nuts P, I. in place after the desired adjustment is made. The caps Nand N are provided atv their upper ends with annular shoulders N, N, adapted to be seated on similar shoulders D D formed in the chambers D D so as to limit the desired movement of the caps N and N, as will be readily understood by reference to Fig. 1. \Vhen the caps N and N are in their lowermost positions, then their seats N N project into the chambers C and C, and when the valves F and F are lifted by the action of the cams I and I then the seats F, F move in engagement with the seats N N so that the passage between the chambers C, C and the valves F, F is closed. When the valves F and F are lifted-to their full extent, the caps N and N after closing the valves are likewise lifted against thetension of the spring 0 "and 0, so that the caps firmly close the upper ends of the valves F and F, to prevent leakage of the motive agent to or from the working chamber of the cylinder A. When the valves F and F are lowered, the caps N and N move downward with the said valves until their anvalves F and F alternately, to properly.

control the passage ofv the motive agent to and from the working chamber of the cylinder A.

The lower ends of the chests D and D are connected with pipes Q and Q, 'of which one is the admission pipe for the admission of the live motive agent, and the other is the exhaust pipe.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: 1

1.. A va lve mechanism for engines, comprising zt'hollow valve for the passage of the motive agent, ayieldingly mounted cap for engagement by the said valve to close one end thereof, and means for imparting movement to the said valve.

2. A valve mechanism for engines, comprising a-hollowmovable valve for the pas.- sage of the motive agent and'provided at one endwith a valve seat, a spring-pressed movable cap having a valve seat for engagement by the valve seat of the said valve to close or open the latter, and means for actuating the said valve.

3. In combination with an enginecylinder having-a chamber for the passage of the motive agent to or from the said cylinder, a hollow valve mounted to slide and provided at one end with a valve seat extending into the saidchambeiga second chamber arranged on top of the first mentioned chamber, a cap mounted to slide in said second chamber and having'a valve, seat adapted to be en. gaged by the said seat on the valve, aspring arrangedin said second chamber and'p'ressv the said chamber,

- screwing in ing the said cap, and means for imparting movementto the said valve. i 4. In combination with an engine cylinder having a chamber for the passage of. the motive agent to or from the said cylinder, a hollow valve mounted to slide and provided at one end with a valve seat extending into 0 a second chamber arranged on top of the first mentioned chamber," a cap mounted to slide in said second chamber and having a valve seat adapted to be en gaged by the said seaton the valve, a spring in said chamber pressing the said cap; a nut the upper end of'said chamber and engaging the spring for adjusting the tension of the spring, and ineans for imparting movement to the said valve. H

5. In an engine, the combination of an engine cylinder having a chamber for the passage of. the motive agent to and fromthe said cylinder, a chest opening into the said chamber, a hollow valve mounted to slide in the said chest and through which the motive agent passes,. aspring-pressed cap having alimited sliding motion and in axial alineout of ment with the said valve, and means foractuating the said engagement with the said cap. valve mechan sm for engines, com- 'A/ copies of this patent may be obtained for valve to move the latter in and ed to slide in the valve chest and throu h which the motive agent passes, a yielding y agent passes, the said'valve being provided movable cap closed atone end and having a valve seat at said end for'engagement by the latter, the said valve.- 4 v 8. The combination with an engine cylinder having an admission and an exhaust chamber connected therewith,,of valve chests opening into the said chambers, hollow valves mounted to slide in the said valve chests, springpressed caps having a limited sliding motion and in axial alinement with the'sald valves, and means for actuating the said valves to 'move the latter alternately into and out of engagement with the said ca s. 1

' In an engine, the combination withan engine cylinder having an admission and an exhaust chamber connected respectively with the working chamber of \positesidesthereof, of valvechests opening into the said chambers, hollow valves mount- ,ed to slide in said chests and through which and means for actuating ing'provided at'their upper ends with valve seats, chambers arranged on the top .of the admission and exhaust chambers, caps mounted to slide in said. chambers and provided at their lower ends with valve seats adapted to beengaged by the valve seats on the said valves, springs held in the said cap chambers and pressing on the said caps, nuts screwing in the upper ends of said cap chambers and engaging the springs to' reg ulate the tension thereof, means for locking the nuts in place, and means for actuating the valves to move the same into and out of ngagement with the said caps.
